What this 3VA1032-4ED36-0JH0 is and what it does
The Siemens SENTRON 3VA1032-4ED36-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a TM210 thermal-magnetic overcurrent release. It carries a rated continuous current Iu of 32 A at ambient temperatures up to 50 °C — no derating needed in a typical 40 °C panel — and begins derating above 55 °C, reaching 28.8 A at the 70 °C operating maximum. Breaking capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That's enough to interrupt high-fault conditions on most commercial and industrial secondary distribution without cascading upstream — the 415 V figure covers common 400 V class panels. Rated insulation voltage Ui is 800 V. The breaker includes a built-in shunt trip (STL) for remote tripping, plus 2 auxiliary switches and 1 trip alarm switch (HQ configuration). The auxiliary release is ordered separately as 3VA9688-0BL32. No undervoltage release, no communication module, no phase failure detection — this is a straightforward thermal-magnetic MCCB for conventional feeder or branch protection.
Lifecycle and sourcing reality
The SENTRON series carries CE, UL, and IEC certifications per Siemens standard practice. RoHS and REACH declarations are available from the manufacturer upon request.
Deployment context and panel integration
The breaker measures 130 mm high by 76.2 mm wide by 70 mm deep. The front face is rated IP40 — protected against tools and small solid objects, but not sealed against moisture. Mount it inside a panel with a door or cover; it is not intended for open washdown areas. The 3-pole footprint is standard for a 32 A MCCB, so it fits existing SENTRON or comparable DIN-rail or screw-mount backplates. A voltage trigger and trip indicator are present on the front, allowing quick visual confirmation of a tripped state during fault isolation — no need to break the seal to check.
